Yeah. She conspired to commit terrorism, but she did not get to carry out any attacks.

The only reason, in the Danish system, that she should have gotten a higher sentence was due to her not being willing to admit that what she conspired to do was wrong, which among other things suggest an unbalanced mind that needs treatment.

Afaik there are guys and girls in Denmark that aren't ethnically Danish that have gone and actually fought and killed for ISIS that didn't get 8 year sentences.
